Abstract
The utility model relates to a closed security coke wet quenching pre-negative pressure device. The device is characterized in that a coke quenching car of a coke quenching device enters a sealed space, namely a coke quenching chamber, automatic doors are mounted at both sides of the coke quenching chamber, and after the coke quenching car completely enters the coke quenching chamber, the automatic doors arranged at both sides of the coke quenching chamber are closed. An automatic valve is mounted on a connection pipeline between the coke quenching chamber and a vacuum storage tank and the automatic valve is opened while the automatic doors of the coke quenching chamber are closed. At the time, a large-scale storage tank is vacuumized by virtue of a vacuum pump while air in the coke quenching chamber is exhausted. Water gas is produced by virtue of high-temperature coke in the coke quenching car and spray water in a spray device and a pressure is formed; since air in the coke quenching chamber is exhausted by the vacuum pump and produced water gas can be exhausted, the coke quenching chamber is maintained at a negative pressure state. By controlling the water amount in the spray device, the produced water gas can be exchanged with the exhausted water gas, thus the security is greatly improved and the harmful substances produced in coke quenching are prevented from releasing to the atmosphere and the pollution to environment is reduced.
Description
Technical field
The present invention relates to a kind of coke quenching device, at enclosed space, spray specifically the pre-negative pressure device of the safe coke wet quenching of a kind of sealing of quenching.
Background technology
Coking industry is the important auxiliary industry of Iron And Steel Industry, through years development, still exists layout unreasonable, produce and disperse, and disorderly competition, the problem that concentration degree is low, coking production environmental pollution and the wasting of resources are still very serious.In recent years, more domestic enterprises blindly enhance production capacities, and occur that supply exceed demand in domestic market, the situation of world market finite capacity.Existing coal chemical enterprise, owing to being subject to the strict demand of environmental protection and the restriction of < < coking industry entry criteria > >, has been taked more advanced Pollution abatement measure.But still have some enterprises can not meet pollutent standard and total amount emission request, cause the environmental pollution of Chan Jiao district serious, therefore, the processing condition of formulating strict pollutant emission standard are to control the most effective means of pollutant emission.Aspect current topsoil environmental requirement improvement, it is being a great difficult problem, the quenching of the spray water of metallurgy industry cooling at present adopts conventional wet method low discharge, the quenching of lower velocity splashing type mode, because current coke quenching device is open type, so carbon monoxide, water, hydrogen, dust that during quenching, high temperature produces are all released in atmospheric layer, environmental pollution is very serious.
Summary of the invention
The advantage of apparatus of the present invention is to compare traditional coke quenching device; make quenching car be in an airtight negative pressure space (coke quencher); quenching car is after entering this airtight negative pressure space (coke quencher); high temperature coke spray water produces water-gas; water-gas enters large-scale vacuum storage tank because the negative pressure in space is sucked away at once; improve security, externally do not produce pollution, protected environment.
Technical scheme of the present invention is:
The quenching car of coke quenching device enters an airtight space-coke quencher, automatically-controlled door is equipped with in both sides in coke quencher, when quenching car enters after coke quencher completely, both sides automatically-controlled door is closed, on connecting tube between coke quencher and vacuum storage tank, automatic valve is housed, automatic valve is opened when coke quencher's automatically-controlled door is closed, and now vacuum pump vacuumizes large-scale storage tank, takes the air in coke quencher away simultaneously.The high temperature coke of quenching car and the spray water of spray equipment produce water-gas mineralization pressure, because vacuum pump Dui coke quencher bleeds, can take the water-gas of generation simultaneously away, and Jiu Shi coke quencher remains on the state of a negative pressure like this.Control the water yield of spray equipment, the water-gas of generation and the water-gas of extraction can be exchanged, so just greatly improved security, guaranteed that the objectionable impurities that quenching produces is not discharged in atmospheric layer, has alleviated environmental pollution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
The pre-negative pressure device of the safe coke wet quenching of a kind of sealing, by quenching car 1, , enclosed space (coke quencher) 2, spray equipment 3, automatic valve 4, vacuum pump 5, large-scale vacuum storage tank 6 and vacuum fan 7 form, between coke quencher 2 and large-scale vacuum storage tank 6, pipeline connects, automatic valve (4) is installed on connecting tube, vacuum pump (5) pipeline connects large-scale vacuum storage tank (6), coke quencher (2), quenching car 1 enters coke quencher 2, the automatically-controlled door of coke quencher 2 both sides is closed, the spray water of the high temperature coke of quenching car 1 and spray equipment 3 has produced water-gas mineralization pressure, automatic valve 4 is opened, vacuum pump 5 vacuumizes large-scale vacuum storage tank 6 by pipeline simultaneously, make pressure in coke quencher 2 in pre-negative pressure state, the effect of vacuum fan 7 is standby when vacuum pump 6 is taken out the interior air of incomplete coke quencher 2.When vacuumizing, extract the water-gas producing out.The water spray of spray equipment 3 is controlled.When quenching car 1 has just entered coke quencher, water spray is little, and the water-gas amount of generation is also few.Slowly strengthen water spray, to guarantee that the water-gas of generation and the water-gas of extraction exchange, Jiu Nengshi coke quencher is in the state of a negative pressure always like this, has so just improved security, guaranteed that the objectionable impurities that quenching produces is not discharged in atmospheric layer, has alleviated environmental pollution.
This practicality does not relate to partly all prior aries that maybe can adopt same as the prior art and is realized.
